Question

What are the coordinates of the center of the circle whose equation is

Answer 1

the standard equation of the circle is

`(x-h)^2+(y-k)^2=r^2`

here, h & k is the centre coordinate.

the given equation is

(x -9)^2 + (y + 4)^2 = 1

(x -9)^2 + (y - (-4))^2 = 1

compare this equation with standard form

h = 9 & k = -4

so the centre's coordinate is ()
